iPhone video quality appears much better than taking a still photo of the same scene

When taking a video of a scene like say a beach for example, there appears to be more details in the video than if I take pictures of the exact same scene. In fact, to get a better quality image, I have shifted to taking a short video and snipping a frame than taking a photo.

All I do is point and shoot the video with no adjustments but even making adjustments with the photo, I can’t get it to look as good. The photos don’t look bad, but they just don’t have what I would say the dynamic range of the photos do or the details. Not sure if others experience this but if you take a photo of say a house plant and then take a video and pan over the plant, the video looks better on both the iPhone 12 Pro Max’s I have tested and I have no clue what is happening here because I can’t seem to find any information as to why this is happening.
